Let's divide 159894 by 79
The aim is to understand the frequency of 79 in 159894.

Moving on to step 1:
The number 79 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 79

Let's proceed to step 2:
When dividing 15 by 79, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 79

Advancing to step 3:
The number 79 fits into 159 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 158 from 159 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 79

Going ahead to step 4:
79 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 79

Let's proceed to step 5:
79 can be fit into 189 2 times, resulting in a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtracting 158 from 189 leaves us with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 79

On to step 6:
79 can be fit into 314 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 2023.0
Subtract 237 from 314 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
79 goes into 770 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 2023.9
The remainder is 59 after subtracting 711 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 8:
If we divide 590 by 79, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 2023.97
Subtracting 553 from 590 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
79 goes into 370 4 times with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 2023.974
Subtract 316 from 370 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 79 fits into 540 6 times, leaving a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 2023.9746
Deduct 474 from 540 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 79, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 2023.97468
Deduct 632 from 660 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
280 divided by 79 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 2023.974683
Deduct 237 from 280 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
79 goes into 430 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2023.9746835
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
When dividing 350 by 79, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 2023.97468354
Subtract 316 from 350 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 2023.97468354 and a remainder of 3.4e-08.
